FIELD: nuclear physics and equipment.
SUBSTANCE: invention relates to nuclear power engineering and can be used in reactors with direct conversion of energy into electrical power. Active zone of nuclear reactor includes at least one module, as well as solid and liquid neutron moderators. Module comprises housing, at least one heat pipe, at least one fuel element and heat insulation. Heat pipe is made in the form of a body equipped with a wick, and contains heat carrier. Fuel element is made of nuclear fuel located in heat pipe evaporation zone around its housing in thermal contact with it and enclosed in shell. Thermal insulation is placed between the shell and the module housing. In solid neutron retarder there is at least one hole in which at least one module is arranged. Space between module housing and solid neutron moderator is filled with neutron liquid suppressor.
EFFECT: higher efficiency of reactor installations and wider field of use of the active zone.
